CCDS Pressure Ulcers and Wound Care Documentation 1 — Questions and Answers
Question 1: Which staging system provides the basis for ICD-10-CM pressure injury code assignment?
- Wagner Grading System
- National Pressure Injury Advisory Panel (NPIAP) staging (Correct answer)
- Braden Scale score
- PUSH Tool measurement
Correct answer: National Pressure Injury Advisory Panel (NPIAP) staging
ICD-10-CM pressure ulcer codes are structured around the NPIAP staging system (Stage 1–4, unstageable, and deep tissue pressure injury).
Question 2: What condition must be documented for a pressure ulcer to be coded as 'unstageable' in ICD-10-CM?
- The physician documents the ulcer cannot be visually assessed due to eschar, slough, or necrotic tissue (Correct answer)
- Any wound that is clinically difficult to treat
- A wound exhibiting undermining or tunneling beyond its edges
- Any pressure wound that was present on admission
Correct answer: The physician documents the ulcer cannot be visually assessed due to eschar, slough, or necrotic tissue
A pressure ulcer is coded as unstageable when eschar, slough, or necrotic tissue covers the wound bed, preventing visual determination of wound depth.
Question 3: Why is a CDI query regarding present-on-admission (POA) status especially critical for pressure injuries?
- Ambiguous POA status for pressure injuries can result in HAC designation, affecting reimbursement and quality scores (Correct answer)
- POA status affects only the length of stay calculation
- POA queries are routine for all diagnoses and carry no special significance for pressure injuries
- POA status for pressure injuries is automatically determined by admission nursing notes
Correct answer: Ambiguous POA status for pressure injuries can result in HAC designation, affecting reimbursement and quality scores
Hospital-acquired Stage 3 and Stage 4 pressure injuries are CMS-designated HACs, meaning ambiguous POA documentation can trigger financial penalties and quality metric impacts.
Question 4: Which statement best describes ICD-10-CM anatomic site options for pressure ulcer coding?
- Only three anatomic sites are recognized: sacrum, heel, and hip
- Only six sites are available, limiting specificity
- Multiple specific sites are provided including sacrum, coccyx, hip, buttock, heel, ankle, and others (Correct answer)
- Only two sites (sacrum and heel) are clinically significant for coding
Correct answer: Multiple specific sites are provided including sacrum, coccyx, hip, buttock, heel, ankle, and others
ICD-10-CM provides distinct pressure ulcer codes for numerous anatomic sites, enabling precise documentation and code assignment for each wound location.
Question 5: A patient is admitted with a Stage 2 pressure ulcer that progresses to Stage 3 during the hospital stay. What stage should be coded?
- Stage 3, the highest stage documented during the admission (Correct answer)
- Stage 2, the stage present on admission
- Stage 3 only if it developed after 48 hours
- Both Stage 2 and Stage 3 are coded separately
Correct answer: Stage 3, the highest stage documented during the admission
Per ICD-10-CM guidelines, when a pressure ulcer advances in stage during the encounter, the highest stage documented during that admission is the code assigned.
Question 6: A patient with diabetes has a foot ulcer. What documentation elements must the CDI specialist verify for accurate code assignment?
- Type of diabetes and the depth/severity of the ulcer (Correct answer)
- Type of diabetes only, since all foot ulcers are coded the same
- Only wound measurements and wound care orders
- Only the treatment plan and specialist consulted
Correct answer: Type of diabetes and the depth/severity of the ulcer
Diabetic foot ulcer codes in ICD-10-CM are combination codes requiring documentation of the diabetes type (Type 1, Type 2, other) and ulcer depth (skin, fat, muscle, or bone involvement).
